TECHNICAL FIELD

The present invention relates to improvements on ergonomic keyboards to transmit instructions, messages to computerized devices, computer-implemented methods, data entry terminals, electromechanical typewriters, electronic consoles, cash registers, or the like apparatuses.

BACKGROUND

In original typewriters, each key was attached to a lever. Each row was arranged diagonally to leave space for the adjacent row of keys. There have been designs of ergonomic keyboards that attempted to give keyboard users efficient results wherein the keyboard is divided into two angular sections with gable angles. These keyboards can be more specifically described as “fixed-split Keyboards”, “adjustable-split keyboards”, and “contoured keyboards” as shown in is shown in U.S. Pat. No. 8,289,684 (2012). U.S. Pat. No. 2,040,248 (1936) issued to August Dvorak and U.S. Patent No. US20140152568 (2014) attempted to rearrange characters which caused learnability difficult. Yet the zigzagged or staggered layout of the keys has virtually remained unchanged for over 140 years.

US patent D387, 340 in FIG. 1 strives to achieve a design with features that provide improving access to keys. Keys are arranged in non-staggered patterns. Such ergonomic design provides consistent key arrangement between rows, enhancing the movements of the fingers and cognitive learning experience, while maintaining QWERTY keyboard layout to inspire keyboardists to adapt to the new key arrangement with minimal efforts.

Studies have shown that the QWERTY keyboard distributes workloads unevenly among fingers, causing the weaker fingers such as little fingers to be strained leading to low productivity. See e.g., How to learn typing on the US standard 101 keyboard known as a QWERTY keyboard. http://www.powertyping.com/qwerty.html, 2010. In traditional keyboards, keyboardists' hands are bent outward to accommodate the tight space of the home rows between the left and the right hands. The fingers of both hands are forced to move diagonally at the same angle as illustrated in FIG. 2. The linear key arrangement in QWERTY keyboard places the keyboardists' writs at a skewed angle that contributes to postural muscular strain and/or a leading cause of ulnar deviation disorders for some keyboardists.

As illustrated in FIG. 4A, frequently used editing, navigating, modifier, or miscellaneous keys are positioned in the integral section of the keyboard. This key arrangement distributes the amount of typing to the index fingers and thumbs of both hands. The space in the integral section expands the distance between the two hands which further enhances the keyboardists' wrists and hands postures.

The isosceles trapezoid keys in the integral section guide a plurality of central keys of the left hand and right hand sections at an angle that reduces the unnatural postures which believed to lead to elevated pressure inside the carpal tunnel and to strain muscle structures. The integral section integrates between the left and the right sides, creating an area of the isosceles trapezoid that gives the modifier or control keys their unique shapes. Unlike fixed-split and adjustable-spit keyboards with a gap or an “intermediate zone” between the left and the right sections, the middle section is an integral part which provides a cohesive key arrangement that maximizes accessibility and work load distribution for all fingers of both hands. This factor is useful for cognitive learning and transitioning to the present invention.

Researchers have reported that pressure inside the carpal tunnel is elevated when the wrist is extended or when the hand is bent upward. See e.g., W. Marklin, Simoneau, and F. Monroe's “Wrist and Forearm Posture from Typing on a Split and Vertically Inclined Computer Keyboards. Human Factors, 41(4), 559-569 (1995). The ergonomic keyboard provides a built-in palm rest by extending the front face of the keyboard housing to construct a platform for the palms of the hands to rest on in such a way that is natural to wrist extension posture. The planes of the keys are lower to the built-in palm rest to further allow the wrists to be at the neutral angle.

SUMMARY OF THE DISCLOSURE

Some embodiments have attempted to improve deficiencies in the QWERTY keyboard by rearranging the alphabets and special characters. Some embodiments split the QWERTY keyboard into separate sections with a gap in between. However, these embodiments have not been widely accepted because of the difficulties in production, learnability, adaptation, usefulness, and cost-effectiveness.

In accordance with embodiments of the present invention that comprises a plurality of an ergonomic keyboard that provides a natural flow of the fingers for the keyboardists to have efficient wrists, hands, and arms postures; and effective key arrangements, in which typing activities are distributed to stronger fingers and thumbs. In addition to the elevated keyboard housing, the built-in palm rest provides supports to the keyboardist' palms so that the writs are positioned at an optimal angle.

In another aspect of the present invention, a set of heuristics for sensing one or more finger contacts of one or more keys and/or the integral section for directing the cursor or mouse pointer, vertical or horizontal scrolling, navigating of screens, graphics, items, windows, masks, forms, records, or other objects in the user interface, transmitting instructions to one or more processors to perform specific functions predefined by the manufacturer, operator.

In accordance with embodiments of the present invention that comprises modular layers of various materials to create customizable and cost-effective design.

Furthermore, the present invention with energy efficient engineering that composes elevated housing in combination with low profile keys to allow modular LED lights to project controlled lighting and LED germicidal ultra-violate (UVC) lights to the surface of the key caps with fewer LED lights in comparison to conventional keyboards that have LED lights for each individual key.

Other characteristics of the present invention are described below.
